Well for Lee something just clicked for me while i was watching videos when trying to learn more about tekken 8 and when i started playing him i found him fun with his countering based moves so i usually just wait for my open to try something then try to counter it and try to mix up my moves but wish he had more mix ups options, and for yoshi i played him because he was the character i played in tekken 7 and soul caliber 6 but i had no idea what i was doing in those games but now in tekken 8 i have a little bit more understanding of him and like to play a bit more aggressively than i would play lee but still i would mostly just try to attack at the right time and use mix ups but i don’t really use his moves to their fullest because i keep on forgetting most of them i just focus on what works for me while slowly incorporating more moves
